PHOTOCATALYST-COATED BODY

摘要

Disclosed is a photocatalyst-coated body that is superior in photocatalytic degradability while reducing the amount of photocatalyst included in a photocatalyst layer. The photocatalyst-coated body is provided with at least a base material, a photocatalyst layer comprising photocatalyst particles, and an intermediate layer disposed in between the aforementioned base material and the aforementioned photocatalyst layer so as to come into contact with the bottom of the aforementioned photocatalyst layer. The aforementioned intermediate layer comprises at least silicon-modified resin and a minimum of one type of bead chosen from a group consisting of resin beads, hollow glass beads and hollow ceramic beads. Said beads form a projection at the interface between the aforementioned intermediate layer and the aforementioned photocatalyst layer, wherein said projection is caused by the shape of the interface.
